An improved apparatus for the aversive conditioning of cigarette smokers

An apparatus is described which permits the presentation of an aversive stimulus (smoke) and a reinforcing stimulus (fresh air) in such a way that it is possible to control their respective latencies and durations. Verbal stimuli may also be presented conjointly with the aversive and reinforcing stimuli. This apparatus was designed to overcome the shortcomings in previous investigations by permitting a more systematic approach to the study of the factors relevant to successful behaviour therapy with addicted smokers. Nine subjects completed a course of aversive conditioning and four were found to be totally abstinent after 6 months follow-up. The weaknesses of the present technique are pointed out and possible improvements briefly noted. In particular, a “broad spectrum” behavioural approach to smoking is advocated.     

The septum and hyper-reactivity: a review

The literature related to one form of septal dysfunction - hyper-reactivity - is reviewed. The increase in reactivity following septal damage is considered in terms of its reliability and the many factors which influence its attenuation and release. Research discussed includes the topics of anatomical locus of septal damage, species and strain investigated, pre- and post-operative handling, neurochemical factors, and the relationship of hyper-reactivity to other septal dysfunctions and other anatomical structures.     

On-line analysis of the GSR

This study reports the use of the λ, a measure of sequential dependency developed by Lathrop (1964) in connection with electrodermal activity. Thirteen female subjects, ranging in age from 19 to 53, participated in a simple repeat-stimulus habituation experiment: GSR data in percent-change and λ were compared. A high, positive correlation was obtained. Consequently, the use of λ is advocated because it shows both initial value and sequential dependency and meets the criteria for analysis based on the probability of statistics such ast andF.     

The effect of change in sequential visual stimuli on GSR adaptation: II,the novel stimulus as a disinhibiting stimulus

GSR records were obtained for 20 Ss presented with a series of 80 stimuli (four lights alternating in apparent random sequence). Records were obtained, also, for 20 Ss in each of two groups, using the same procedure: in Group 1, a tone was substituted for one of the lights, early in the sequence, and in Group 2, it was substituted later in the sequence. The tone, the novel stimulus, produced significant changes in the GSR adaptation patterns of the two groups.     

Stimulus novelty and intraseries primacy in GSR adaptation

GSR records were obtained for four groups of 20 Ss. Group I was presented with a series of four different lights (amber, blue, green, and white) appearing 20 times each, in apparent random order. The procedure was similar for the other three groups except that in group 2, a novel stimulus (a red light) appeared instead of the sixth amber light; in group 3, it appeared instead of the 16th amber light; and, in group 4, it appeared instead of the 16th amber light. Typical GSR adaptation phenomena were observed in all groups. The introduction of the novel stimulus appeared to have no effect on the course of GSR adaptation.     

Filling of the Circle of Willis in carotid angiography using halothane anesthesia

A comparative study of 150 carotid angiographies carried out under local anaesthesia and the same number under halothane anaesthesia did not show any great deviation from the well-known filling rates of the counter-lateral carotid region and the ipsilateral A. cerebri posterior nor any striking differences in the two methods of anaesthesia which could convince of a favourable influence of halothane on the demonstration of the vessels. The causative factors of the filling of adjacent vascularisation regions can certainly only be explained from the complex co-action of physiological and any external factors in cerebral angiography.     

Work centrality and post-award work behavior of lottery winners

Individuals who had won the lottery responded to a survey concerning whether they had continued to work after winning. They were also asked to indicate how important work was in their life using items and scales commonly used to measure work centrality. The authors predicted that whether lottery winners would continue to work would be related to their level of work centrality as well as to the amount of their winnings. Individuals who won large amounts in the lottery would be less likely to quit work if they had relatively greater degrees of work centrality. After controlling for a number of variables (i.e., age, gender, education, occupation, and job satisfaction), results indicated that work centrality and the amount won were significantly related to whether individuals continued to work and, as predicted, the interaction between the two was also significantly related to work continuance.     

Reducing the Effects of Stereotype Threat on African American College Students by Shaping Theories of Intelligence

African American college students tend to obtain lower grades than their White counterparts, even when they enter college with equivalent test scores. Past research suggests that negative stereotypes impugning Black students' intellectual abilities play a role in this underperformance. Awareness of these stereotypes can psychologically threaten African Americans, a phenomenon known as “stereotype threat” (Steele & Aronson, 1995), which can in turn provoke responses that impair both academic performance and psychological engagement with academics. An experiment was performed to test a method of helping students resist these responses to stereotype threat. Specifically, students in the experimental condition of the experiment were encouraged to see intelligence—the object of the stereotype—as a malleable rather than fixed capacity. This mind-set was predicted to make students' performances less vulnerable to stereotype threat and help them maintain their psychological engagement with academics, both of which could help boost their college grades. Results were consistent with predictions. The African American students (and, to some degree, the White students) encouraged to view intelligence as malleable reported greater enjoyment of the academic process, greater academic engagement, and obtained higher grade point averages than their counterparts in two control groups.     

Juvenile curfews: are they an effective and constitutional means of combating juvenile violence?*

Curfew ordinances have become a popular way to attempt to combat juvenile crime and victimization. Although the Supreme Court has yet to hear a curfew case, several constitutional challenges have been brought in lower federal courts. The cases are replete with psychological assumptions for which there is limited empirical evidence. In applying the "strict scrutiny" standard, several courts have also questioned whether juvenile curfews are narrowly tailored to further the State's interest in reducing juvenile crime and victimization. While public opinion and reports from several police jurisdictions support the utility of juvenile curfews, recent empirical studies indicate that curfews are not effective at reducing juvenile offending or victimization. This paper argues that the emerging evidence does not support the use of juvenile curfews and urges policy makers and the courts to examine the efficacy of curfew legislation. Directions for future research that could be helpful to the courts in applying the Bellotti factors to curfew cases are also suggested.     

The Psychiatrist and the Dying Patient by Kurt R. Eissler

Abstract

In this study behavioral processes in the individual and group therapies of aggressive boys were compared and the relationship between these variables and treatment outcome was examined. Level of aggression was the outcome variable, measured by both self-report and teacher-report instruments. Hill’s Client Behavior System (CBS; Hill, 1986) with our own ad hoc categories of Reference to Literary Figures and Response to Another, and therapist Helping Skills System (HSS; Hill &; O’Brien, 1999) were the behavioral process measures. In terms of the boys’ behaviors, discriminant function analyses revealed that Reference to Literary Figures and Response to Another differentiated the treatment formats; with regard to therapists’ behaviors, Questions and Challenge differentiated the modalities. Results offered partial support for the greater effectiveness of group, compared to individual, therapy in reducing aggression. Outcome, however, as measured by teacher reports of aggression, was adversely affected in group therapy by the presence of specific behaviors in the boys. Implications of the findings for modifying the group therapy program as well as for the search for process variables appropriate to the treatment of aggressive children are discussed.
